• Voltage monitoring range: 0.8V to 5.5V
• Reset timeout period: Adjustable from 1ms to 640ms
• Low quiescent current: Typically 6µA
• Small package size: SOT-23-3
• RoHS compliant

Package and Quantity

ADM1810-5AKS-RL7 is available in a SOT-23-3 package, which is a small surface-mount package with three pins. It is typically sold in reels containing a specified quantity of units.

Specifications

• Supply Voltage Range: 0.8V to 5.5V
• Reset Threshold Voltage: 4.63V (typical)
• Reset Timeout Period: Adjustable from 1ms to 640ms
• Operating Temperature Range: -40°C to +85°C

Pin Configuration

ADM1810-5AKS-RL7 has three pins arranged as follows:

```

---

| | --| RESET |-- --| GND |-- --| VCC |-- |_______| ```

Pin Description: - RESET: Output pin that generates a reset signal when the monitored voltage drops below the threshold. - GND: Ground reference pin. - VCC: Power supply input pin.

Functional Features

• Voltage Monitoring: ADM1810-5AKS-RL7 continuously monitors the supply voltage and compares it to a preset threshold.
• Reset Generation: When the voltage falls below the threshold, the device generates a reset signal on the RESET pin.
• Adjustable Timeout Period: The reset timeout period can be adjusted using external timing components.
• Power-On Reset: The device ensures a proper reset signal is generated during power-up.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various systems.
• Adjustable reset timeout period provides flexibility for different applications.
• Low quiescent current minimizes power consumption.
• Small package size enables space-saving designs.
• RoHS compliance ensures environmental friendliness.

Disadvantages

• Limited reset timeout period range may not suit all application requirements.
• SOT-23-3 package may pose challenges for manual soldering or rework.

Working Principles

ADM1810-5AKS-RL7 operates by continuously monitoring the supply voltage. When the voltage drops below the preset threshold, the device triggers a reset signal. This reset signal remains active until the voltage rises above the threshold or the adjustable timeout period elapses. The device ensures a reliable power-on reset during system startup.

Application Field Plans

ADM1810-5AKS-RL7 finds applications in various electronic systems where voltage monitoring and reset functionality are crucial. Some potential application fields include: - Microcontrollers and microprocessors - Embedded systems - Industrial control systems - Communication equipment - Automotive electronics
